Test Dusts

Test Dusts: Industry Standard Test Dusts & Product Testing by DMT

DMT GmbH & Co. KG offers test and standard dusts for various sectors of industry and areas of application, from filter technology to the automotive industry.

As well as manufacturing of a range of test dusts, which we ship worldwide, our specialists perform simulation and detailed testing of the dusting behaviour of many products according to standardized particle size distribution. This includes air filters, vacuum cleaners and other household appliances. Internal quality controls guarantee that our test results comply with legal standards. Thanks to many years of cooperation with our suppliers, you also benefit from a consistently high-quality result.

Our test dusts and standard dusts comply with international standards and include:

DMT test dusts

DMT Test Dust Type 8®

This synthetic vacuum cleaner test dust specified in the standard DIN IEC 60312 is used, among other things, to determine suction performance loss when the vacuum cleaner bag is filled. In terms of its characteristics this dust simulates real house dust with respect to separation in the vacuum cleaner bag. The specifications along with quality control of the raw materials used and the test dust produced from that guarantee a high level of quality. This means the physical characteristics, such as dust cake structure and the propensity for clogging of vacuum cleaner parts, are reproducible from test to test. In contrast to contaminated house dust, DMT’s test dust is free of pollen, fungi, bacteria and any toxic substances.

Dolomite: Testing of floor coverings

Mineral vacuum cleaner test dust for testing dust absorption of various types of flooring, such as carpets and parquet, as well as of various textiles like upholstered furniture, wall coverings, etc. (testing, for instance, as per DIN IEC 60312). This quartz-free material has a standardised particle size distribution.

Slate Flour: Dust emission according to DIN IEC 60312

Slate flour is used to determine the dust emission of vacuum cleaners in accordance with DIN IEC 60312. Furthermore, tests (determination of degree of separation) are conducted on air filters, e.g. vehicle filters, air cleaners and ventilation systems for vehicle cabs (landfill vehicles), using this dust (ISO 12103, DIN ISO 5011, etc.). This material containing quartz has a standardised particle size distribution and in this respect as well as in terms of its chemical composition corresponds to AC fine (ISO 12103-1).

ASHRAE Standard 52.2 Test Dust

The test dust we offer complies with the definition specified in the ASHRAE 52.2 (formerly 52.1) standard in terms of composition, particle size distribution and fibre length distribution. The test dust produced is subjected to a batch-by-batch outgoing goods inspection.

ARAMCO Standard Test Dust

We also offer the two test dusts according to the definition of the ARAMCO standard (32-AMSS-008).

Arizona Test Dust according to ISO 12103-1

Arizona test dust is produced to ISO 12103 standard. Made of Quartz, it is available in ultra fine (A1), fine (A2), medium (A3) and coarse (A4).

Customised dusts on request

Do you need a test dust with special properties, for example particularly abrasive particles, special particle size distributions or special materials? We would be pleased to advise you. On request other dusts are available and we can produce special dusts according to your requirements.
